我正在嘗試使用 tkinter 在 python 中可視化正弦波加法，并且我正在嘗試在每個(gè)圓中心之間建立線，但是到目前為止我嘗試過(guò)的并沒(méi)有像我想象的那樣工作。有沒(méi)有辦法解決我嘗試過(guò)的問(wèn)題（見代碼），或者有辦法只移動(dòng)一條直線的一個(gè)坐標(biāo)點(diǎn)與另一個(gè)坐標(biāo)點(diǎn)嗎？如果您運(yùn)行它，您將在代碼中看到，我嘗試了一種方法，其中每次迭代前一行都被擦除并創(chuàng)建一個(gè)新行。當(dāng)我運(yùn)行代碼時(shí)，就像我想要的那樣，每個(gè)圓圈的中心之間實(shí)際上有一條線，但事實(shí)是這些線持續(xù)存在并且不會(huì)自行擦除；出于某種原因，似乎 canvas.delete(line) 不像我預(yù)期的那樣工作。這是完整的代碼。有趣的部分是在 'updateline' 函數(shù)中，進(jìn)入 'act()' 函數(shù)。import mathimport tkinter as tk##important to know! -- the way I'm creating the circles is by setting an object, the bounds of the circle, depending on amplitude asked by user.##then the programs calculates the path of these bounds, depending on circles, amplitude, phase and frequency of the sine waves asked by the user from the tkinter GUI.##finally, the program creates and moves along this path a circle, representing visually the sine wave.top = tk.Tk()top.title('Superposition')choice = tk.Tk()choice.title('Parametres')f = tk.Frame(choice,bd=3)f.pack(side='top')g = tk.Frame(choice,bd=3)g.pack(side='bottom')tk.Label(f,text="nbre ondes:",width = 10).grid(row=0,column=0)sines = tk.Spinbox(f,from_=1,to=50,width=10,textvariable=tk.DoubleVar(value=2))sines.grid(row=0,column=1)sines.delete(0,5)sines.insert(0,2)delai = tk.Scale(g, orient='vertical', from_=100, to=1,resolution=1, length=100,label='delai')delai.grid(row=0,column=0)hauteur = tk.Scale(g, orient='vertical', from_=1100, to=100,resolution=100, length=100,label='fenetre')hauteur.grid(row=0,column=1)taillec1 = tk.Scale(g, orient='vertical', from_=3.5, to=0.1,resolution=0.1, length=100,label='taille')taillec1.grid(row=0,column=2)delai.set(20)hauteur.set(600)taillec1.set(1.5)def grilledechoix():    numberofsines = int(sines.get())    for i in f.grid_slaves():        if int(i.grid_info()["row"]) > numberofsines+2:            i.grid_forget()我預(yù)計(jì)一旦 updateline 函數(shù)再次調(diào)用自身，這些行就會(huì)消失，因?yàn)?'canvas.delete(line)' 行進(jìn)入了 updateline，我真的不明白它為什么會(huì)這樣做。無(wú)論如何，如果您有使線條移動(dòng)的解決方案，而無(wú)需在每次調(diào)用函數(shù)時(shí)創(chuàng)建和刪除它們，請(qǐng)隨時(shí)告訴我。
